Is it allowed to smoke cannabis on the street?

I recently heard it was forbidden, but looking at the information about what is allowed for weed on Utrecht.nl (for example, max 5 grams a day per person) Also other websites, but I couldn’t find any mention if it’s forbidden to smoke weed on the street. Is it allowed or not? P.S.: If you’re gonna say it’s not allowed please provide a source for this information, thanks ;)
